A bullet of mass m = 40 g, moving horizontally with speed v, strikes a clay block of mass M=1.33 kg that is hanging on a light inextensible string of length L=0.767. The bullet becomes embedded in the block, which was originally at rest. What is the smallest value of vv which would cause the block-on-a-string to swing around and execute a complete vertical circle?

A bullet of mass m = 40 g, moving horizontally with speed v, strikes a clay block of mass M = 1.73 kg that is hanging on a light inextensible string of length = 0.774. The bullet becomes embedded in the block, which was originally at rest. What is the smallest value of v which would cause the block-on-a-string to swing around and execute a complete vertical circle?

[This is a particularly challenging problem, incorporating momentum, conservation of energy, and centripetal force. If you find yourself getting annoyed, just remember that I could have turned the block into a projectile as well :-). Consider it a bonus.] A bullet of mass m = 40 g, moving horizontally with speed v, strikes a clay block of mass M = 1.68 kg that is hanging on a light inextensible string of length L = 0.620.

See the picture (This is a particularly challenging problem, incorporating momentum, conservation of energy, and centripetal force. If you find yourself getting annoyed, just remember that I could have turned the block into a projectile as well :-). Consider it a bonus.) A bullet of mass m = 40 g, moving horizontally with speed u, strikes a clay block of mass M = 1.45 kg that is hanging on a light inextensible string of length L = 0.770. The bullet...
26) In Figure 8.4, a bullet of mass 0.01 kg moving horizontally strikes a block of wood of which is suspended as a pendulum. The bullet lodges in the wood, and together they swing upward a distance of 0.40 m. What was the velocity of the bullet just before it struck the wooden block? The length of thestringis2 meters. A) 646 m/s B) 366 m/s C)423 m/s D)250 m/s E) 66.7 m/s 667m-
QUESTION 7 A bullet of mass 40.0 g moving with a speed of 249 m/s strikes a block of wood of mass 2.00 kg and becomes imbedded in it (stuck inside it). The block had been originally at rest and is free to move. What is the speed of the block and bullet immediately after the collision, in units of m/s? QUESTION 10 If an object is initially at rest and then 'explodes' into two separate pieces, what do we...
A 35 g bullet is fired horizontally into a hanging wooden block (mass 1.7kg) as shown in (Figure 1). The bullet's initial speed is 300 m/s . The bullet becomes embedded in the block, which then swings upward some height. What is the maximum height to which the block rises? Instead of getting embedded in the block, the bullet passes completely through it, emerging on the other side with a speed of 100 m/s . How high does the block...
A 70g bullet moving east at 40 m/s strikes a 1.2kg block suspended and becomes embedded in the block. How high will the bullet-block system rise above its original point?
11. A bullet moving at 200 m/s strikes a wooden block which has several hundred times the bullet's mass. The block is hanging from a string. Only 1% of the kinetic energy of the bullet shows up as motion of the block after the bullet has become embedd ed in the block. What happened to the rest of the energy? Describe how the block moves and some of the changes to the block.
A 2.00-g bullet hits and becomes embedded in a 5.00-kg wood block which is hanging from a 1.20-m long string. This causes the block to swing through an arc of 3.50°. What was the speed of the bullet before it hit the block?
